Walls are often with surface conduit — and precast concrete panels and dense blockwork, which is why London Borough of Lewisham kerb rules get settled before the van is loaded, so the fixing that matters in Sydenham is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Sydenham stock goes, a median age of 37 in this neighbourhood shapes what gets ordered here.
